Birch Boys Chaga Chunks are a great value. Each box contains golf-ball-sized Chaga Mushroom Chunks. You can freeze and reuse each chunk up to 4 times. If you’re looking for Chaga Chunks for sale then look no further than Birch Boys.

Why choose Wild Chaga? Wild Chaga can take years to grow naturally, all the while absorbing and concentrating a variety of healing compounds from the Birch tree. Cultivated chaga (sometimes not even grown on birch) only takes a few days/weeks to grow and will not contain the full spectrum of healing compounds found in real, wild chaga. If you’re searching for quality chaga mushroom for sale, choose wild chaga!

I’m really enjoying Chaga Chunks! Making Iced Tea with it by the pitcher and I add fresh Lemon. Delicious and so good for us all!

Great benefits with Chaga Chunks

I finally purchased the Bag of Chaga Chunks and measured out 1gallon of water, added 2 smaller chunks and seeped for 3 hrs. My apt smelled so so good. I’ve been using the Chaga Water in my morning coffee and WOW! It really adds a nice light flavor also with my French vanilla cappuccino. I have only been drinking this daily for 1week, anxious to reap the benefits from Birch Boys Chaga Chunks. Can’t wait to try their skincare mist.
